Several Monte Carlo (MC) event generators are used to simulate signal and background events. The NLO  (v2) [1]}, [2]}, [3]}
generator is used for events, assuming a value of 172.5for the top quark mass (\(m_\text{top}\) ).
These events are passed to  (v8.205) [4]}, [5]}
to simulate parton showering, hadronization, and the underlying event, using the CUETP8M1 [6]}, [7]} tune for the default MC sample.
The NNPDF3.0 NLO PDFs with strong coupling \(\alpha _\mathrm {s}(M_{})=0.118\)  at the Z boson mass scale \(M_{}\)  are utilized in the MC calculations.
